Voltage Regulators-Linear is an electronic device used to convert an unstable DC voltage into a stable DC voltage. It regulates the voltage through an active component (such as a transistor or field effect tube) and a feedback network to ensure that the output voltage remains constant within a certain range. Linear regulators usually operate under low input voltage changes and load changes, and are able to provide a very clean and smooth output voltage.

Voltage Regulators-Linear has a wide range of applications, covering almost all electronic devices requiring a stable DC power supply. In the field of consumer electronics, linear voltage regulators are widely used in mobile phones, tablets, laptops and other portable devices to provide stable voltage support for core components such as processors, memory and display screens. In the field of industrial automation and instrumentation, linear voltage regulators are often used in precision measuring instruments, sensor signal processing and other occasions because of their low noise and high precision characteristics. In addition, linear regulators also play an indispensable role in areas such as medical equipment, aerospace, and automotive electronics, where the quality of the power supply is extremely high. For example, in medical equipment, linear regulators ensure the power stability of devices such as pacemakers and monitors, ensuring the safety of patients.

• 1. What are the disadvantages of linear regulators?

  The disadvantage of linear regulators is that they are not efficient and can only be used in voltage reduction applications. The efficiency of a linear regulator depends on the ratio of output voltage to input voltage: turbidity = Vo: Vi. For example, for ordinary linear regulators, when the input voltage is 5V and the output voltage is 2.5V, the efficiency is only 50%. For ordinary linear regulators, about 50% of the electrical energy is converted into "heat" and lost, which is also the main reason why ordinary linear regulators are prone to heat when working. For LDO, due to its low voltage difference, the efficiency is much higher. For example, when the input voltage is 3.3V and the output voltage is 2.5V, its efficiency can reach 76%. Therefore, in LCD color TVs, in order to improve the utilization rate of electrical energy, ordinary linear regulators are used less, while LDOs are used more.

• 2. What are the three types of voltage regulator?

  The three types of voltage regulators include the contact voltage regulator, the transistor regulator and the integrated circuit regulator.
  Contact voltage regulator: This is the type of voltage regulator used earlier. Its working principle is based on the vibration of the contact, but there is mechanical inertia and electromagnetic inertia, resulting in low voltage adjustment accuracy. Large, poor reliability, and short life, so it has been eliminated.
  Crystal tube regulator: With the development of semiconductor technology, the transistor regulator becomes the mainstream. It uses a triode for voltage adjustment. Compared with the contact -type voltage regulator, the advantages of the transistor regulator is that the response speed, high efficiency, small volume, light weight, and not easily affected by external magnetic fields are widely used.
  Integrated circuit regulator: Integrated circuit regulator is a new type of voltage regulator developed in recent years. It integrates mult

• 3. What are the two main categories of linear and switching stabilizers?

  The two main categories of linear and switching stabilizers are linear voltage voltage power and switching voltage power supply.
  Linear voltage voltage power has achieved the advantages of transformer, rectification, filtering, and voltage voltage. It has the advantages of good stability, fast transient response speed, high reliability, and high output voltage accuracy. However, its transformation efficiency is low, especially when the output voltage difference is large, if the output current is also large, there will be obvious fever and hot phenomenon, and may even burn the regulator. The linear voltage voltage power supply includes two types: fixed output voltage and adjustable output voltage. According to the selection of the output current and the difference in the input output voltage difference, the design of the linear regulator needs to pay attention to the heat dissipation problem and the choice of bypass capacitors.
  The switching voltage voltage power supply, also known as
